Abstract

A survey of numerical methods for the calculation of inviscid Euler flows is presented. This survey has been prepared for AGAKD FDP WGOT: "Test cases for steady inviscid transonic or supersonic flows". The survey is augmented by a short assessment of the usefulness of the methods. For aerodynamic applications, the existing methods are in a number of respects accurate and cheap enough. However, shocks and vortex-sheets may have to be better modelled to achieve higher numerical accuracy. Computation times can be reduced by applying multigrid methods.
